Maybe we were to close when we got the "stampede" effect from those pigs we lit up. Hey do you mean a lot when you say a lot.I have the Big Red set up from Texas Boars and it is awesome. The pigs do not see in the red spectrum{ If you are too close they can see the source , but it looks like a grey orb} and they do not notice the illumination.
The scope lights are so so but if you are close enough{ under 50 yards} they are alright.
I do kill a lot of pigs, and by a lot , I mean a lot.
Good luck.
Maybe we did make noise with the light I can't remember wind direction but it was most likely in our face.
